This invention relates to heaters, an ob-' ject being to provide meansfor utilizing the heat of the sun rays for heating water. Another objectof the invention 1s the provision of a heater of this character which isconstructed of sections arran ed so that one ormore sections will bepositioned transversely of the direct rays of the sun as the lattertravels across the horizon, together with means for directing the sunsheat upon a rece tacle or container for water or other liqui and toprovide a circulation through the receptacle. v

With the above and other objects in view, the invention further includesthe following novel features and details of construction to behereinafter more fully descrlbed, illustrated in theaccompanyingdrawings and pointed out in the appended claims. In the drawings Figure1 is a top plan view of a solar heater constructed in accordance withthe present invention.

Figure 2 is a sectional view on the line 22 of Figure 1.

Figure 3'is an enlarged section on the line 3-3 of Figure 1.

Figure 4 is a top plan view of the outer panel of one of the top wallsections.

Figure 5 is a plan view of the inner panel of one of the top wallsect1ons.

Figure 6 is a detail plan view shown a different form of liquidreceptacle or coi Figure 7 is a side view of the coil shown in Fi re 6.

Re erring to the drawi s in detail wherein like characters of re erencedenote corresponding parts, the heater which-may be placed in anyadvantageous position, is shown as supported upon the top of a building,a portionof which is indicated at B. The heater comprises a supportingframe 10 and a housing 11, the latter being of suitable configuration.This housing comprises a bottom wall 12 and side walls 13. The top wallof thehousing is indicated at 14 and is shown as comprising a horizontalsection 15' which has extending from its opposite edges, oppositelyinclined sections 16. 50 The sections 16 are arranged at a suitableangle, the purpose being to provide a maximum amount of surface forexposure to the suns rays irrespective of the position of the sun, andwithi a e a y ma area Located beneath and spaced "from the'top wall 14is a receptacle 17. This receptacle 1 is preferably of the sameconfiguration as the top wall 14 and is adapted to contain water orother liquid 18. Located within 1 the housing between the bottom of thewall of the receptacle 17 and the bottom wall 12 of the housing is alining of heat insulating material 19. The receptacle is provided withan inlet 20 and outlets 21 and these inlets and outlets may be connectedrespectively with a suitable source of water supply and with receptaclesor the like to which the heated water may be conducted.

Thetop wall 14 is of novel construction, each. of the sections beingformed of an inner panel 22 and an outer panel 23. These panels areprovided with openings which are surrounded by flanges 24, the flanges24 of one of the panels being telescopically received within the flanges24 of the other panel. Passages 25 are thus provided through the topwall 14.' Located at the outer ends of these passages are seats 26 whichreceive magnifying lenses 27, the latter being held in place by fingers28 which extend from around the edges of the openmgs of the'outerpanels. The wall 14 is spaced from the top wall of the receptacle 17 andthis space provides a heat chamber 29 with which the passages 25communicate. An unobstructed passage for the suns heat from the lenses27 is thus provided for the upper wall of the receptacle 17, so thatwater within the said receptacle may be heated within a relatively shorttime. By reason of the relative angles of the sections of the top wall14, a maximum amount of this wall will be presentedto the rays of thesun as the latter moves over the horizon while heat within the chamber29 may circulate through this chamber over the surface of the receptacleeven though one of v the end panels 16 is not exposed to thediinreserved to make such changes as proper- 1 fall within the scope vofthe appended c aims.

- Having claimed '1S2- 1. In a sun power water heater, a housin a topwall for the-housing, said wall inclu ing sections-arranged at difierentangles,

--a receptacle located within the housing whereby .one or more sectionswill be tioned transversely of the direct rays the sun as the lattertravels across the horizon,

vneath the top wall, a heat insulating linin between the receptacle andbottom wall 0 the housing and lenses arranged within the section of thetop wall of said housing.

2. ha sun ing, a top wa for the housing, said wall including sectionsarranged at different angles, whereby one or more sections will bepositioned transversely of the direct rays of the sun as the lattertravels across the horizon, a receptacle located within the housingbeneath the top wall, a heat insulating lining between the receptacleand'vbottom wall of the housing, and lenses arranged .within the sectionof the top wall of said housing, the inner faces of the lenses being oposed to the top'of the receptacle to provi e an unobstructed passage ofheat through the lens to the receptacle.

3. In a sun ower water heater, a housing, a top wall or the housing,said wall including sections arranged at diflerent angles, whereb one ormore of said sections will be positioned transversely of the direct raysof the sun, as the latter travels across the horizon, a receptaclelocated within the housing beneath the top wall and having the sameconfiguration as said top wall, a heat insulating lining between thereceptadescribed the invention what is I power water heater, a hous 1zon, a receptacle located withinthe housing beneath the top wall andbeing spaced from said wall provide a heat chamber, a heat insulatingllning between the receptacle and bottom-wall of the housing, and lensesarranged within the sections of of said housing.

5. In a sun wer heater, a housing, a top wall for the ousing, said wallcomprising spaced inner and outer panels having openings therein,flanges surrounding the openthe top wall ings, with the flan es ofonepanel telescopically received within the flanges of the other panel andproviding heat passa es, seats at the outer end of the passages, ensesupon the seats, means engaging the lenses to hold thelatter in position,a receptacle within the housin and an insulating lining between theottom of the receptacle and the bottom of the housing. a

6. In a sun power eater, a housing, a top wall for the housing, saidwall comprising a horizontal section and o positely inclined sectionsextending from t e horizontal section, a receptacle located'within thehousing beneath the top wall, a heat insulating liningbetween the recetacle and bottom wall of the housin and enses arranged within thesections 0 the top wall of said housing.

In testimony whereof I ailin my signature.
